Definitions

  • the present invention relates to a drive apparatus for a conveyor system, particularly a belt conveying system used for transferring articles from one location to another.
  • Conveying systems are well known in the art and have any number of uses and applications.
  • Typical conveying systems utilize a flat conveying belt, generally formed of interconnected links, driven by motors that engage with the conveyor belt.
  • the motor With typical systems, the motor will drive a toothed drive sprocket that engages with complimenting driving recesses or dogs formed on the conveyor belt.
  • These drive units can be disposed in any number along the length of the conveyor belt.
  • US-A-2 150 610 shows such a known device.
  • the present invention relates to an improved motor drive unit, and conveyor system incorporating the motor drive unit, wherein the driving load is distributed over several rows or links of the conveyor belt. Accordingly, it is a principal object of the present invention to provide an improved motor drive unit or apparatus for use with a conveying system.
  • Still a further object of the present invention is to provide an improved motor drive apparatus that is capable of distributing the driving load over adjacent rows or links of a conveying belt anywhere along the conveying path of the belt.
  • Yet another object of the present invention is to provide an improved motor drive apparatus for use with any manner of conveying system in any conventional application of the conveying system.
  • a conveyor drive unit for engaging and driving a belt-type conveyor.
  • the conveyor drive unit can be used with any conventional belt conveyor.
  • the belt conveyor is a conventional belt formed by interlocking plastic, or other suitable materials, links that define a generally flat conveying surface.
  • the conveyor drive unit includes a motor drive that may incorporate any conventional motor.
  • a drive chain assembly is provided having a drive chain driven by the motor along a drive path.
  • the drive chain assembly may include any number and configuration of drive sprockets, idler sprockets, tensioning sprockets, tensioning rollers, etc.
  • the drive chain includes drive lugs configured thereon to engage with complimenting drive dogs configured on the conveyor as the drive chain is driven along the drive path.
  • the drive path defines a drive angle with respect to a straight path of the conveyor along the drive path.
  • An adjustable positioning device is disposed relative to the drive chain assembly wherein upon variable positioning of the device, the drive chain assembly is adjusted and the drive angle correspondingly varies. In this manner, the degree of engagement of the drive lugs with the drive dogs of the conveyor along the drive path can be adjusted by varying the drive angle.
  • the conveyor drive unit includes support structure.
  • the drive chain assembly, positioning device, and other components of the drive unit may be mounted on the support structure.
  • a carriage is movably mounted on the support structure and the drive chain assembly includes drive and idler sprockets mounted on the carriage.
  • the positioning device is mounted on the support structure and engages with the carriage to vary the drive angle by changing position of the carriage.
  • the drive path is preferably defined between the drive and idler sprockets.
  • the carriage may be pivotally mounted on the support structure at a pivot point, with the positioning device engaging the carriage generally opposite from the pivot point.
  • the drive chain assembly includes an idler sprocket and a drive sprocket
  • one of the idler or drive sprockets is displaceable or movable relative to the other sprocket so as to vary or change the drive path of the drive chain which is defined between the idler and drive sprockets.
  • the idler sprocket may be mounted on a movable carriage, with the positioning device in engagement with the carriage to change the drive angle by changing the relative position of the idler sprocket relative to the stationary drive sprocket.
  • the positioning device may comprise any manner of device, including a manually adjustable mechanism, for example a simple screw type mechanism.
  • the positioning device can comprise any manner of automatic or power device, including electric, hydraulic, or pneumatic engaging devices.
  • the drive chain assembly includes drive and idler sprockets that are disposed in a generally horizontal plane with the drive path defined between the drive and idler sprockets.
  • the conveyor drive unit is generally disposed beneath the conveyor to engage the drive dogs on the conveyor from below along the drive path of the drive chain.
  • the present invention also encompasses a conveyor system utilizing the conveyor drive unit assembly as described above.
  • the invention may include a belt conveyor having spaced apart drive dogs configured on a bottom surface thereof. Any manner of conventional belt conveyor may be utilized in this regard, including conventional plastic link belt conveyors.
  • the conveyor drive unit is disposed relative to the conveyor so as to engage the drive dogs and move the conveyor in a desired direction.
  • the conveyor drive unit may include any of the embodiments described herein as well as various modifications thereof.
  • the present invention relates generally to a conveyor drive unit for any manner of conventional conveyor belt, particularly plastic belts made from modules or links having drive dogs thereon for being engaged by drive lugs or rollers on a driven chain.
  • a premise of the present invention is that superior driving results can be achieved by angling the path of the drive chain relative to a straight conveying path of the conveyor, and also by angling the drive surfaces of the conveyor belt drive dogs.
  • the pitch of conventional conveyor belts tends to vary under load and over time (i.e., the belt collapses and expands with load variations and tends to expand over time).
  • the problems with such conventional drive units may be compensated for by varying the pitch of the drive chain to accommodate for the changes in pitch of the conveyor belt links.
  • the present invention provides a unique solution.
  • Any conventional conveyor belt is illustrated as belt 12 having drive dogs 32 disposed thereon, for example on a bottom surface of belt 12.
  • Drive dogs 32 have a drive face 58 defined thereon.
  • drive dogs 32 are defined on alternate or spaced apart interconnected links of conveyor belt 12. There is an inherent degree of "play" between the links, which also contributes to change in pitch between drive dogs 32.
  • Conveyor 12 is driven in a generally straight conveyor path indicated by arrow 22.
  • conveyor unit 10 includes a driven drive chain 24 having a plurality of spaced apart drive lugs 30 disposed thereon.
  • Lugs 30 may comprise drive rollers 54 (Fig. 3) for engaging drive dogs 32 and moving conveyor 12 in its conveying direction.
  • Conveying chain 24 engages with conveying belt 12 along a drive path.
  • the drive path may be defined between an idler sprocket 18 and a drive sprocket 16.
  • the actual drive path is indicated by the dashed line 23 in Figures 4A and 4B, and also by arrow 20.
  • Drive path 23 defines an angle 34 with respect to the conveyor belt path 22.
  • Drive angle 34 is adjustable, as described in greater detail below, between 0° and an angle less than 90°.
  • drive angle 34 is such that chain 24 has an inclined "angle of attack" with respect to drive dogs 32.
  • drive lugs 30 engage against drive faces 58 at a relatively bottommost point as drive lugs 30 come off of idler sprocket 18 and move towards drive sprocket 16.
  • the lugs move up on drive faces 58. Due to this change in the vertical component caused by drive angle 34, the effective pitch or horizontal spacing of the drive lugs 30 varies along the drive path 20.
  • this arrangement causes a greater number of drive lugs 30 to remain in driving engagement with drive dogs 32 along the length of drive path 20, and allows for a smooth and vibration reducing engagement and release between drive lugs 30 and drive dogs 32.
  • drive faces 58 on drive dogs 32 are also angled (non-perpendicular) with respect to a flat or horizontal bottom surface of conveyor belt 12. This angle is indicated as reference character A in Figures 4A and 4B where it can be seen that drive faces 58 are angled in the conveying direction of the conveyor. Because of this angle of the drive faces, as the drive lugs 30 move up drive dogs 32 along drive path 20, they are forced into further engagement with each drive dog 32, which further accommodates for any change in spacing or pitch between the conveyor belt links.
  • angle 34 of drive path 20 and the angle A of drive faces 38 contribute to effectively vary the pitch of drive chain 24 without actually physically changing or modifying drive chain 24 along the length of drive path 20.
  • a useful angle configuration is to have the angle of drive faces 58 equal to the maximum angle of adjustability of drive path 20.
  • angle 34 may be adjustable between 0° and 6° and drive faces 58 may have an angle of 6° so that when drive angle 34 is at its maximum, drive path 20 is perpendicular to drive faces 58.
  • FIG. 1-3 One preferred embodiment of structure for carrying out the present invention is illustrated in Figures 1-3. It should be appreciated that this is but one example of suitable structure and that any number of structural modifications and variations may be incorporated in the invention.
  • conveyor drive unit 10 includes a motor drive 14, which may comprise any conventional type of drive motor, preferably a conventional electric motor.
  • a drive chain assembly, generally 15, having a drive chain 24 is configured with motor 14 so that drive chain 24 is driven along the conveying path.
  • drive chain assembly 15 includes any arrangement of drive and idler sprockets disposed so as to define the drive path as discussed above.
  • drive chain assembly 15 includes an idler sprocket 18 spaced apart from a drive sprocket 16.
  • a motor chain 26 is disposed around a primary drive 52 that is coupled to motor 14 through any conventional gearing arrangement. Motor chain 26 directly drives a sprocket 28.
  • a tensioning sprocket 46 may be provided on motor chain 26.
  • a drive sprocket 16 is mounted for rotation with sprocket 28.
  • drive sprocket 16 may be mounted on a common axle with sprocket 28.
  • drive sprocket 16 and idler sprocket 18 comprise double or stacked sprockets.
  • Drive chain 24 is disposed around drive sprocket 16 and idler sprocket 18.
  • a tensioning roller 48 may be provided to supply and maintain an appropriate tension on drive chain 24.
  • Drive chain 24 is driven along drive path 20 that is defined generally by rails 31.
  • Drive chain 24 includes support tabs 33 that extend generally transversely from drive chain 24 and which ride upon rails 31 along drive path 20.
  • Drive chain 24 also includes spaced apart drive lugs 30 for engagement with drive dogs 32 on the conveyor, as described above.
  • Drive lugs 30 may take on any conventional configuration, but are preferably drive rollers 54 as particularly illustrated in Figure 3.
  • the pitch or spacing of drive lugs 30 is essentially constant since chain 24 is a heavy duty metal or steel chain and the links are generally not susceptible to change due to load, stress, age, etc.
  • Conveyor drive unit 10 also includes an adjustable positioning device, generally 36, that is operationally configured or disposed relative to drive chain assembly 15 so as to change or reposition some component thereof causing drive angle 34 between drive path 20 and the generally straight conveying path of conveyor 12 to vary. It should be appreciated that there are any number of ways to change this drive angle. For example, the relative position between either of the idler or drive sprockets 18, 16 could be changed relative to the other resulting in a change in the drive angle.
  • conveyor drive unit 10 includes support structure 38 having the components mounted thereon. Support structure 38 can comprise any manner of framing or support devices. A movable carriage 40 is mounted on structure 38.
  • Carriage 40 may be movable in a plane such that drive angle 34 is varied.
  • carriage 40 is pivotally mounted relative to a pivot point 42 that also coincides with the axle of idler sprocket 18.
  • Positioning device 36 engages carriage 40 to pivot or move the carriage causing the relative position of drive sprocket 16 to change relative to idler sprocket 18. It should be appreciated that the reverse configuration is just as feasible.
  • the adjustable positioning device 36 is illustrated in the figures as a simple mechanical screw type of device wherein a bolt or screw 44 is engaged with carriage 40 such that manual adjustment of screw 44 causes carriage 40 to pivot or change position.
  • Any manner of well-known engaging or moving members may be utilized, for example, a solenoid type device, hydraulic device, pneumatic device (all of which may be automatically adjustable) and are within the scope of the invention.
